SharePoint security broken between Microsoft 365 group and SharePoint group
Hi, Users are giving Member privilege through Teams, which gave them Member privilege in the Member SharePoint group. All good for 99% of the company. PROBLEM : I have 4 users without access...

If you're referring to those Private channel sites when users are members of the private channels get removed from the "Members" sharepoint group then its worth checking those users' RecipientTypeDetails and ensure they are not SharedMailboxes.
If they are, convert to UserMailbox and see the issue persists.
Had a few clients > they checked and found that to be the case > the suggestion fixed the issue for them.

Hi TheChosen1 !
I have no Private channel associated with this Microsoft 365 Group / SharePoint, I don't even have a Teams. I have also thousands of these Microsoft 365 Group / SharePoint combinaison, and no problem with them. Only 4 users who seem to lost access after they have been initialy granted the right to some of them.
